The lifespan decider
When specs are close, support length decides it — this is what each phone costs per month of safe use.
Category by category
Both displays are effectively the same class.
Performance is a wash — same chip tier.
The X100 Ultra has the stronger camera system — same lens count, higher-grade sensors.
5,500mAh vs 5,000mAh — the X100 Ultra lasts longer between charges.
The X100 Ultra is supported until May 2029 — 7 months longer than the iQOO 12.
